Fig. 4 is a fragmentary enlargedlsectiwnal viewtaken on line IVIV ofFig. 3;

Fig. 5 is a fragmentary section'al-wiewiof the upperportion of thecommodity support- Like reference characters desi tesimilar partsthroughout the several VIGWS and'the numeral 10 designates a scale framemounted onwheels 20, andhaving a pillar 1:1 and a beam 13 on which issupported the wei'ghtmo supporting member '14 and a sliding 15.Positioned on the front of pillars 11 -is a rack 16 adaptedtoreceive-the reserve Weights 17. The Weighing platform 18 is mounted inthe usual manner so 'that the weight'of articlemer) placed thereon maybe readily determined 'by the proper manipulation of- *thepoiseandWeights.

The platform scale shown and described is the ordinary scale usedinstores wheremom 'qo modities are sold by weight; Many oommodities are ofpeculiar'size and sh'ape,s\ich as bananas on the stemete, so thattheycan not be readily placed on the-platform dor weighing. Also, theplatfonn-"gets -"soileF and dirty so that it is notsuitablefor thereception of commodities-such as meatgete, which are notordinarily"providedwvith a cover. p

' It is the object of this invention to provide so a suitable supportingdetachable device by means of which such commodities may' be supportedduring the operation of weighing.

The body portion or standard 25-of'the commodity supporting device is ofinverted s5 'U-shape including legs 21 and with a vertically extendingsocket member 22 projecting'upwardly therefrom. 25is preferably made oftubular material with the lower ends thereof threaded at 23 to receivenuts 24. The lower portion of each of the legs'21 issecured to platform18 by means of a clamping device provided with an elongatedthinfootmember 26 having a shoulder '27 adapted to rest against theouter edge of the platform and" which is provided with a verticallydisposed opening 28throughwhich 21passes. Amadjustab-le clamping member29 having a hole 30 through which 21 loosely fits is so positioned below26 thatit extends inwardly-andais pro vided with an upturned portion 31to engage the rim 32 on 18. The outer end of 29 hasan upturned lug 33that fits loosely into a recess 34 formed in the under side of 26. Screwthreaded in 26 with its head extending thereabove is an adjusting screw36 which is adapted tobe adjusted to press downwardly on lug 33 so that29 may be rocked on nut 35 carried by 21 to force 31 upwardly to theclamping position. 7 v A To mount the standard 25, the nut'35 is adjusted so that when the adjusting screw is screwed outwardly 31 will beseparated from 26 a sufiicient distance to: permit the clamp to beslipped over the rim 32 after which 36 fscrewed. downwardly against33until 29 securelyclamps the rim and secures the standard against "anymovement relative to the platform 18., It will be noted that 21 is $0threaded a sufficient distance to permit adjustment of nuts 24 and 35 toallow sufilcient adjustment between 26 and 29 to span platform rims ofdifierent thicknesses.

I Rotatably mounted in socket ,22 is the jdownturned stem 37 of ahorizontally disposed supportingarm 38 which'is adapted to v beselectively positioned directly over the platform 18 or at the sidethereof; Stem 37 is provided witha set collar 39 having a set 7 so screwwhich-is adjustable on the stem to ;vary .;the height of 38 above theplatform. Arm38 18; provided at its outerend with a supporting hook 41and a pair of adjustable j hooks 42 adapted to be adjusted at anydesired position thereon and secured against rotation by means of setscrew 43. To secure ,the arm .38 against accidental rotation collar v39is provided with a tooth'44which engages one of the series of notchesformed in the 49; upperend of 22. l/Vhen it is desired to rotate 38 itis lifteduntil 44 disengages 45 then the arm may be positioned andsecured against rotationrby dropping 44 in the adjacent notch. Forreinforcing the arm 38 a 45 dlagonal brace rod '48, rigidly secured to38 at 46 and rotatably mounted on 22 to'bear 'against anadjustable setcollar 47 so as to V -take' the downward thrust, is provided.

When the height of the arm 28 above the 59 platform is varied it isapparent that the set collar will necessarily be changed to proper- 1ysupport the lower end of 48. 'When the supporting device is positionedon the scales it is necessary to add a weight 50 on14 to properlybalance the scales. Howa ever, this may be done by adding shot to thecounterbalance in the usual manner.

With the construction as shown and deqscribed, it isfapparent that thethin foot mempart of the platform for supporting commodities to beweighed, also that the stand ards are carried beyond the end of theplatform. The arm 38 may be positioned over theplatform when being usedor at the Side bers will not interfere with the use of anyv thereof whennot in use. Furthermore, the entire attachment may be readily removedfrom the scale platform as described above.

I do not wish to limit this invention to the structure shown anddescribed as many modifications may be made within the scope. of theappended claims without departing from the spirit thereof.

What I claim is:

1. A commodity supporting device for platformscales, comprising astandard including an inverted U-shaped body portion having a verticallydisposed socket positioned thereon, a horizontally disposed supportingarm rotatably mounted in said socket and adapted to be rotated to andfro na position above said platform. j i
